An apparatus for separating plant material from a stem of a harvested plant includes a frame and a planar sheet attached to the frame having a thickness thereof and an aperture therethrough that has a length defining a longitudinal axis and a width equal to or greater than the thickness of the planar sheet, the width being operable to receive the stem when the stem is pushed through the aperture but to sever the plant material extending from the stem; and a motor-driven blade defining a cutting edge dimensioned for sweeping adjacent to one side of the planar sheet, the cutting edge being aligned with the longitudinal axis when adjacent to the aperture and operable to disintegrate a portion of the stem that protrudes through the aperture to the one side as the stem is pushed through the aperture.

A harvester reciprocating drive balancing system may include a crop material separating member movably supported for reciprocal movement and a drive operably coupled to the crop material separating member to reciprocate the crop material separating member. The drive may include a drive crank operably coupled to the crop material separating member, a shaft operably coupled to the drive crank, a belt drive, a driven pulley, a belt wrapped about the belt drive and the driven pulley and a gear reduction mechanism operably coupled between the driven pulley and the shaft.

An agricultural harvester includes a grain processing section having a sieve assembly. The sieve assembly is driven in fore and aft oscillation by an eccentric rotation device while permitting side to side movement. A drive arm to the sieve assembly has a connection interface to the eccentric rotation device permitting side to side movement during fore and aft oscillation.

A threshing and separating system including a non-stationary rotor cage including a perforated cylindrical body extending in a longitudinal direction from a first open end portion to a second open end portion. The first open end portion supported by a first rotatable coupling point, and the second open end portion supported by a second rotatable coupling point. The threshing and separating system also includes a rotor configured to rotate within the non-stationary rotor cage to thresh harvested crop. The non-stationary rotor cage is configured to rotate about an axis extending between the first rotatable coupling point and the second rotatable coupling point, and to be rotationally driven by the rotor via the threshed harvested crop.

An apparatus for actuating a rocking motion of a movable component including an adjustable length actuator, a lever whose angular position is controlled by the actuator, and a force transfer element attached to the movable component. The lever comprises a pair of oppositely placed pawls shaped so as to interact with the force transfer element for respectively actuating movement of the component in one of two opposite directions, when the lever exits a neutral positional range in which range any interaction between both pawls and the force transfer element is prohibited. The neutral range may be defined by a support plate positioned, shaped, and dimensioned so as to prohibit interaction between the pawls and the force transfer element. The displacement of the component in one direction may be larger than in the opposite direction.
